HENRY MICHAUX, OF NEW YORK, N. Y.

KNIFE-CLEANING MACHINE.

$PEGIFIGATION forming part of Letters Patent N 0. 706,677, dated August 12, 1902.

Application filed April 7, 1902. Serial No. 101,673. (No model.)

To all whom, it may concern.-

Be it known that I, HENRY MICHAUX, a citizen of the United States, and a resident of Figure 1 is a side view of the machine. Fig.

2 is a top view of Fig. 1, and Fig. 3 represents a cross-sectional view of Fig. 1 on line at.

A in the several figures represents the bed of the machine which supports the several parts. It is mounted on legs A and has fixed screws .A for supporting bars B and B, which form a guide or track for the friction-rolls D of the brush-carrying block D.

A represents springs which support the bars B and permit the adjustment of the nuts A for the purpose of readily setting the brush :D to any desired pressure on the article to be polished or to compensate for the wall of the brush.

rolls D to have free play by aid of the blocks B Fig. 1.

A Figs. 1 and 2, is a disk mounted on the arbor A which is supported on the stanchions A This disk is provided with a crankpin A which operates the crank-arm E, pivoted at E to the brush-carrier D.

G is an adjustable bed-plate supported by the studs G and is raised or lowered by the screw A G is a bar held by the stanchions N. This bar in conjunction with the bed G forms a clamp to support and lock the knife-holder H.

H, Figs. 1 and 3, is a knife-holder having a sink for the knife-handle K and a rest for the blade of the knife K.

H is a cap hinged at H to the holder H and is provided with a sink to correspond with the upper part of the handle K.

The bars B and B are kept apart sufficiently to allow the friction- The knife-holder H is held in position by the clamp H whenever the lever O is swung up. D', Fig. 3, is a brush-block secured to the .carrier D, in which are set bristles of any suitable kind.

L represents boxes secured to the carrier D and are provided with covers L and passages L leading through the brush-carrier D and brush-block D, permitting the powder used for polishing to pass to the brush.

(land 0 are copings to prevent the powder from scattering or being wasted as it is thrown oif-the'brush.

The passages A and A are used in cleaning the gathered powder from the receptacle formed by the copings.

The operation is as follows: The knife holder or look H is removed from the machine and the top part H opened. The knives K are placed in the several sinks and the top part H closed. The holder is then passed between the bed G and bar G, as shown in emery, is then put into the boxes L, and the crank A is turned, which operates the brush back and forth over the knife-blades. When one side has been properly cleaned or ground,

the holder is removed and the knives turned in the holder, which is again put in place, as before described.

Having thus fully described my invention, what I claim as new, and desire to secure by Letterslatent, is-

1. The bedAsupporting the adjustable bed G and the screw A the knife-holder H and clamp-bar G, in combination with the reciprocating brush-carrier D having brush D and receptacle L provided with passages L as set forth.

2. The bed Asupporting the adjustable bed G, the stanchions N, the bar G and cam-lever O, in combination with the knife-holder H and the reciprocating brush D having receptacles L and passages L as set forth.

3. The bedA stanchion A bars B and B forming a track for the friction-rolls D the springs A and nut A in combination with the stanchions N bar G cam-lever O, knifeholder 11 and reciprocating brush D asset forth.

4. Thebed A having the copings C and C the arbor A and disk A, operating the rod E and carrier D, in combination with the adjustable bar G cam-lever O knife-holder H brush D and boxes L as set forth.

5. The bed A having screw A screw-stanchions A disk A crank-rod E to operate the brush-carrier D, in combination with the bed G, stanchions N, bar H, cam-lever O, knifeholder H and reciprocating brush D as set 15 forth.

6. The bed A having screW-stanchions A spring A bars'B, blocks 13 bars B and nuts A in combination with the brush-carrier D having rolls D brush D, knife-holder H and 20
